16 GB DDR4 2400 ECC RDIMM

This 16 GB DDR4 2400 ECC registered DIMM is built for HP server and workstation platforms. It targets administrators who need to expand memory capacity on compatible systems. The module uses a 1Rx4 organisation and operates at the standard 1.20 V.

Check system memory specifications

Verify that your server supports DDR4 2400 registered ECC memory in a 288-pin DIMM slot before ordering. Confirm the maximum module capacity and population rules for your specific model. The part replaces HP numbers such as 805349-B21, 819411-001 and 862930-B21.

Steady throughput under load

Registered buffering and ECC correction maintain data integrity during sustained workloads. The CL17 latency and 1.20 V operation keep power draw predictable over long runs. Major-brand chips are tested for reliable continuous operation in multi-socket configurations.

Questions sur cet article

Does the 16 GB DDR4 2400 ECC RDIMM come as a single module or a kit?

The package contains one 16 GB DDR4 2400 ECC RDIMM (288-pin DIMM) — no additional modules or accessories are included.

Should I choose the 1Rx4 rank or a dual-rank alternative for my HP server?

This module is 1Rx4; pick it when your system's qualified-vendor list specifies a single-rank registered ECC DIMM for the target slot population.

What does the PC4-19200 rating mean for actual throughput in a compatible server?

PC4-19200 indicates a 2400 MT/s data rate; the module runs at 1.2 V with CL17 latency and ECC error correction for registered server workloads.
